Cytological Characterisation of Autosomes and Sex Chromosomes in Tephritid Fruit Flies Bactrocera zonata and Zeugodacus tau (Diptera, Tephritidae)
Two fruit fly species, Bactrocera zonata (Saunders, 1842) and Zeugodacus tau (Walker, 1849) (Diptera: Tephritidae) were studied with regard to their autosomes and sex chromosomes from mitotic metaphase spreads. Both species are native to South and South- East Asia and have major economic impacts in...

| description | Two fruit fly species, Bactrocera zonata (Saunders, 1842) and Zeugodacus tau (Walker, 1849) (Diptera: Tephritidae) were studied with regard to their autosomes and sex chromosomes from mitotic metaphase spreads. Both species are native to South and South- East Asia and have major economic impacts in agriculture sectors of these areas. They are polyphagous, can easily adapt and spread. Both of them have the same diploid chromosome number of 2n = 12 (10 autosomes + heteromorphic sex chromosome pair XX/ XY). The male is heterogametic (XY) and the female is homogametic (XX). Chromosomes were classified into groups on the basis of centromere position and arranged in order of decreasing size. For B. zonata, chromosome formula is (3sm + 2m + Xm + Ydot-shape) and for Z. tau, the formula is (1sm + 4m + Xm + Ydot-shape). The results are analyzed and compared to chromosome studies done for other species of Tephritid fruit flies using chromosome morphometrics. Detailed images of mitotic chromosomes and measurements of various parameters relating to these chromosomes are provided. These cytological data are useful for systematics and contribute to a better understanding of the chromosomal evolution of these fruit fly species. |
